I started in 1957. I worked at the telephone co. working nights. I had a 1st class
FCC lic. so I did line ups on Microwave systems and we had microwave ovens even then
and it was a small box used in the microwave system. We heated sandwiches even then
by turning down a spare system and inserting a sandwich in the box. It was just large enough for a sandwich. Had to take off a plate with four screws to insert the sandwich. Just wish I knew at the time what that little box would be worth.
Now on to why I can say I started then is that I had trouble sleeping during the day so I started working as a electrician part time with a co. and at the time very little air condition work but they had some. I worked like this for several years until I retired from the telephone co. which was 1980. Had 23 years in and wanted to do something else. I had already started working for myself in 1974 doing A/C work. I had master electrician lic. and they grandfathered in the A/C lic. I took the schooling as required and last year was my last schooling because I'm now 70 and closed my business. Now I just draw pictures for my hobby. Oh and read HVAC-TALK.
